4. Compressor Operating Range 4-1 Operating Range

Refer to page 8 for the Compressor's Possible Operating Range.

4-2 Precautions

1) Temperature

·Discharge port temperature : 150 max.

·Discharge gas temperature range : Between Condensing temperature + 20°C and 125°C

·Oil temperature : 80°C max.

·Motor winding temperature : 120°C max. (Average temperature based up on

resistance measure of motor winding）

2) Power Supply

·Maximum voltage fluctuation : ±10% of rated voltage

·Maximum frequency fluctuation : ±2% of rated frequency

3) Refrigerant Systems

·Allowable refrigerant charge : 2.5 kg

·Design the refrigerant circuit so that the quantity of liquid refrigerant returning will be minimized.

·Oil concentration in oil sump during operation : Refer to the oil concentration range in 8-6.

·The compressor must be filled with refrigerant through the liquid pipe.

·The compressor may be filled with an excessive refrigerant charge, provided that circuit design is

conducted with an appropriate device, such as an accumulator, is employed so that the

compression mechanism will be free of excessive refrigerant.

·Counter pressure (i.e. Suction pressure – discharge pressure) at pneumatic or leak test

: 1.47MPa max.

4) Others

·Maximum operating times : 12 per hour

·Make sure that the shortest operation period is two minutes or more. Be sure to wait for at least

three minutes to start the compressor after turning it off.

·Mounting Angle : ±10°max.

·Be sure to employ a crankcase heater. The recommendable output is 33 W.

·Liquid height of residual compressor oil during operation should be maintained in the compressor

external bottom at, at least, 17mm.

5. Protection Devices The compressor must be installed with the following protection devices.

5-1 Discharge Pipe Thermostat

Attach a discharge pipe thermostat within 30 cm of the discharge pipe in order to prevent the

temperature of the exhaust gas of the compressor from rising excessively due to overloading or gas

supply interruption. The thermostat must be sensitive to an exhaust gas temperature of 125± 0.5°C .

5-2 Low Pressure Switch

Attach a low-pressure switch operating at a low pressure of 0.02±0.02MPa in order to prevent the

compressor from damage that may be caused by excessively low-pressure pumping.

5-3 Reverse-Phase Protector

The rotation of the compressor in the reverse direction is prohibited because the compressor may be

damaged if rotated in the reverse direction. Attach a reverse-phase protector that detects the phase

inversion of the compressor without operating the compressor.

5-4 Internal Motor Protector

5-5 High Pressure Switch

In order to interrupt the operation of the compressor in the case of extraordinary pressure rises,

attach a high-pressure switch that operates at the pressure values provided as leak test pressure

values in 3-2.
